my buddys truck is a 91 with duals 22re and my old long bed drive line from a 79 -83 long bed bolted right up. but he has 36 irocks front and 36 ssx's tsl in the rear and one other thing well two 79-83 drivelines used 12mm bolts and a little bit smaller u jonts so u would have to change out ur diff flange. because later style drivelines used 14mm bolts and there u joints wont fit 79-83 drivelines
